This invention relates to die carriers for continually operating presses for producing flour paste articles.

With continually operating presses for producing flour paste articles it is usual to provide for the extrusion die for the articles to rest against a solid die carrier and for the arrangement of a distributing device underneath the die carrier operating to divide an air current among the discharging paste articles. Such conventional apparatus have the drawback that the air supplied thereinto from below is compelled to discharge in the downward direction also.

According to the present invention this drawback is intended to be eliminated in that the die carrier is constructed as an air supply conduction means surrounding the discharging flour paste articles at the point of extrusion thereof, in such manner, that the air is directed on to the discharging flour paste articles from the side and is discharged in the downward direction.

In the accompanying drawing an embodiment of the invention is illustrated by way of example only, in which Fi 1 is a vertical section of a die carrier according to the invention;

Fig. 2 is a horizontal section of Fig. l, and

Fig. 3 shows a modification of the air guide means of the die carrier .on a smaller scale.

In the drawing, the numeral I designates the die carrier which is constructed as .an air supply conduction means or air supply channel having a partition wall 2 which guides the stream of air arriving from a fan (not shown) so as to separate it in two :branches. These branch streams are distributed over a cylindrical inner wall 3 which surrounds the flour paste articles at the .point of extrusion thereof and is provided with passages 4 communicating with the channel I, in such manner, that the air is directed on to the paste articles from the side in continuous streamlets without practically forming any eddies and is then discharged downwardly together with said articles, as indicated by stream lines provided with arrows in Fig. 1. Interiorly of the wall 3 a screen 5 is arranged which overlies the air supply passages 4. The screen 5 has the function to uniformly pass the air to the flour paste articles and to prevent particles of paste from entering the channel I. Due to the fact that in this arrangement the die carrier itself is constructed as an air supply channel, the air can be conducted into contact with the extrusion die or die plate. In Fig. 1 the die 6 having extrusion openings 1 is shown as mounted in a die holder ring 8 which is screwed into the paste supply tube 9.

In the modified die carrier shown in Fig. 3, two partition walls 2, 2" are arranged in the die carrier I instead of the single partition wall 2 shown in Fig. 2. With this modified arrangement it is intended to distribute the air supplied into the die carrier still more uniformly to the flour paste articles.

What I claim is:

In a die carrier for a continually operating press for producing flour paste articles, an extrusion die, a carrier supporting said die, extrusion means provided in said die for discharging said articles from said die down through said carrier, an air supply channel arranged in said carrier, a cylindrical wall included in said air supply channel in substantially parallel relation to the direction of travel of said articles discharging from said extrusion means and so as to surround said discharging articles, air supply passages arranged in said wall in communication with said channel and the interior ;of said wall, and a screen overlying said air supply passages on the inside of said cylindrical wall for directing said air supply through said screen on to said discharging fiour paste articles from the side and for said air to be discharged in the downward direction.
